Solitary ovarian plasmacytoma: About a rare entity of extramedullary plasma cell tumor

INTRODUCTION

Solitary ovarian plasmacytoma is a rare form of extramedullary plasmacytic tumor that develops outside the bone marrow.

PRESENTATION OF CASE

We report the case of a 52-year-old female patient who consulted for pelvic pain and abdominal distension. Clinical examination revealed an abdominopelvic mass and a pelvic MRI confirmed a right ovarian mass. The diagnosis of ovarian plasmacytoma was made after exploratory laparotomy.

DISCUSSION

Extramedullary plasmacytoma (EMP) is rare and most often found in the upper aerodigestive tract, ovarian localization is exceptional. Histological and immunohistochemical features of EMP highlights similarities with multiple myeloma. EMP treatment options are discussed, including radiotherapy, surgery, and chemotherapy. The prognosis of EMP depends on several factors, including tumor size and timing of treatment.

CONCLUSION

Solitary ovarian plasmacytoma is a rare but important entity to consider in the diagnosis of abdominopelvic masses. Appropriate treatment, such as surgery combined with radiotherapy, can be effective, although regular monitoring is necessary due to the risk of relapse and transformation into multiple myeloma.

Dysphagia as an Unusual Presentation of Myeloma

Multiple myeloma is a plasma cell dyscrasis characterized by mature B cells proliferation in the bone marrow. In rare cases, the disease can present as an extramedullary location, making diagnosis and management more challenging. Here, we describe a rare case of tongue extramedullary myeloma and discuss diagnostic, prognostic, and therapeutic issues.

Extramedullary plasmacytoma of the cricoid cartilage progressing to multiple myeloma: A case report

Extramedullary plasmacytoma (EMP) is an uncommon tumor of the plasma cells, and EMP of the cricoid cartilage is extremely rare The present study reports the rare case of a 43-year-old male complaining of hoarseness and dyspnea for over a year. Computed tomography imaging of the neck revealed an occupying lesion in the cricoid cartilage, and a diagnosis of EMP was subsequently confirmed by histopathological evaluation. The patient underwent surgery, but refused radiotherapy against medical advice. One year later, the patient was diagnosed with a recurrence of EMP via pathological examination and underwent a second surgery, however, radiotherapy was refused. After a further two years and four months, the patient presented with lumps in the neck, and was subsequently diagnosed with multiple myeloma. The patient received systematic chemotherapy in the hematology department; the patient’s general condition stabilized, and no further anemia, bone pain, infection or other discomfort was experienced. Solitary plasmacytoma of the cricoid cartilage is a rare lesion and compliance with radiotherapy following surgery may provide significant benefit in the treatment of this disease.
